I am in the middle of my upgrade from standard twins to a Garret To4z. (Rb26)

At the moment i am waiting on a few parts like my Exhaust Manifold (6boost) Apexi PFC (greDDy) etc ...

As i live in a bit rural setting, every now and then i get a bit stuck with the certain systems i have never attempted.

My question is How have some of you adapted the oil and water lines to the single turbo application . Any Pic's or links would be fantastic!

I have tried to do a bit of searching about this but keep getting wrong, similar or off track in the threads.

Also i have read that the oil line to turbo needs restricting because it can blow oil past the seals... If so how would i go about getting the right restriction..

All else we think we have covered!!!

thanks ish!

Hi,

It's pretty simple, near as I can tell (I am in the process of doing this right now and it's not finished yet). You

can buy all the relevant fittings from Pirtek (they will either use Speedflow or Motorsport Connections to get

the banjos they don't have).

WATER:

There's a water line going around the back of the motor that tees off to the two stock turbos in a double banjo fitting -

I'm replacing the entire line as the fittings at the back are in the way of my exhaust + gate.

Tee off this to one side of the water feed on the turbo.

There's another two water lines that go to a double banjo on the block - I've replaced this with a single banjo for the other

side of the water feed on the turbo.

I'm not sure which of the water lines are high pressure/low pressure, but I don't think it matters. Put one to one

side and the other to the other.

OIL:

I'm _told_ that the relevant restrictor is already part of the Garrett T04Z. There is certainly no mention in the

documentation of installing further restriction.

There is a single oil double-banjo about halfway up the block that you need to replace with a single banjo fitting.

This banjo is (I believe!) 1.25mm pitch and 10mm - an odd fitting if you want a -3 outlet - I have to use an adaptor.

Use this as your oil feed.

There are 2 oil returns at the bottom of the block; block off the rearmost one with a plate/gasket goo (carefully!)

and use the front one as your oil return. The T04Z comes with a gasket for this but without the fitting - I am

going to make a fitting from a pipe and some plate as I haven't been able to find one.

Make sure you crank the motor without the spark enabled until you get oil coming out the feed line - _then_ bolt

it to the turbo, then crank a few more times before enabling spark.

You will need to get custom lines made up in the diameters and lengths of your choice; I'm using -3 in teflon/braid

high-temp hose for both oil and water. Hopefully this will be sufficient. Or buy a kit with the oil/water lines included -

I don't know whether they include banjos and hollow bolts though.

I'll add some pics to this when I dummy up the bits.

Regards,

Saliya

i think -3 is way too small for the water lines, i always use -8 or -10. If your prepared to do the work yourself, you can always order all the parts from motorsport connections in sydney, They have an online catalogue, The parts will probably came top around $200-250

Hey,

you might be right; I'm just going on recommendations from my friendly Pirtek guy. Will look closer when we actually

go to make the hoses and post photos (should not be too long) and your advice is appreciated...

-8 for water lines is what i used and was reccomended, definately not -3!!!

oil feed is much smaller at around -4 or 5 i think from memory

oil drain is huge at around 3/4 inch pipe or something stupid >_<

restrictor is needed for hks t04z but im 99% sure all garrett turbos have them built in. (from what ive been told anyway)

Yeah, oil drain is huge. If you look @ the factory setup for the GTS-R like my car was (even with the RB25) it had massive drain for the t04e which bolted onto GT30 actuall, direct swap.

Its what i'd be using similar as Cubes said :D

Garrett turbos, the ones that ive seen (GT30 series)... all carry an internal restrictor on the cartidge itself. 0.8mm if i recall correctly.

I am unsure of a HKS model as i have not seen on in pieces.

As your goin Garrett, just check with the supplier... i havent seen a T04z apart... so i cant say 100% that there is an internal restrictor on the cart itself so it would pay to find that point out, unless someone else knows?

Make sure you use teflon lined hose for oil feed, -4 is ample. -6 line is what we use for water and -12 for oil return. Motorsport connections can supply all fittings. will cost around $300. will be able to see if cartridge is fitted with restricter as oil feed hole is phisically smaller.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
